SEE REPLACEMENT PART: OBSOLETE

The Pentair/StaRite SuperMax 2.5HP Diffuser is intended for focused equipment repair when a worn or damaged part needs to be replaced without changing the full assembly. It is used for pump wet-end repair and performance restoration and should be selected when the original part no longer performs as expected. This diffuser component helps manage water movement inside the pump wet end so the impeller can move water efficiently through the system. A worn, cracked, warped, or incorrect diffuser can contribute to poor priming, reduced flow, noise, or loss of hydraulic performance. Match the pump series, horsepower, and part number to the existing component before reassembly. The 2.5HP rating should also be verified against the pump label or service documentation. Before ordering, compare the part number 350170, visible shape, connection style, and model information with the component being replaced. This helps reduce returns, prevents mismatched repairs, and gives the installer a better starting point for restoring normal operation.

Replacement pump component for the model family, horsepower, or series shown in the title.
Useful when restoring flow, priming, debris control, or wet-end performance.
Helps avoid replacing the entire pump when one internal component is damaged.
Confirm the removed part, pump label, and part number before installation.
Inspect gaskets, O-rings, seals, and hardware during reassembly.
